Stereo tape recorder "Aelita MP-7210-S" since 1990 has been produced by Kurganpribor software. The device is almost the complete analogue of MP "Radio MP-7210-stereo" and apart from the presence of a mechanical tape consumption meter it is no different. However, the very first issues of the basic apparatus were counters. The MP is also designed to record phonograms from various sources of the sound signal, with subsequent reproduction through UCU. There are systems of noise reduction and dynamic bias. The speed of the magnetic tape - 4.76 cm / s. Knock factor ± 0,19%. The working frequency range on the LV for magnetic tape with a working layer of Fe2O3 and CrO2 is 40 ... 12500 Hz and 40 ... 14000 Hz. The total weighted signal-to-noise ratio on a magnetic tape with a 54/51 dB CrO2 and Fe2O3 working layer. Signal-to-noise ratio weighted with UWB -60 dB. The ratio of the recorded signal to the erased -60 dB. Mains power. Dimensions of MT 430x358x120 mm. Weight 6 kg. Video about MP on youtube.com.
